How to calculate extended quantity in BOM IMPLOSION QUERY

Question

Hi guys,
I have given an assignment to create BOM  item where used report, For this purpose I am using an BOM implosion API  (PACKAGE.PROCEDURE = BOMPIINQ.IMPLODER_USEREXIT)
I am calling this API like this-
declare
  V_SEQUENCE_ID    number;
  v_err_msg        VARCHAR2(80);
  v_err_code       NUMBER;
  V_DATE           VARCHAR2 (30);
begin
delete BOM_SMALL_IMPL_TEMP;
-- V_SEQUENCE_ID:=142354;
SELECT BOM_IMPLOSION_TEMP_S.NEXTVAL INTO V_SEQUENCE_ID FROM SYS.DUAL;
SELECT TO_CHAR (SYSDATE, 'YYYY/MM/DD HH24:MI') INTO V_DATE FROM DUAL;
BOMPIINQ.IMPLODER_USEREXIT (
        SEQUENCE_ID => V_SEQUENCE_ID,        
        ENG_MFG_FLAG => 1,                   
        ORG_ID => :org_id,             
        IMPL_FLAG => 1,                    
        DISPLAY_OPTION => 1,                    
        LEVELS_TO_IMPLODE => 10,             
        ITEM_ID =>:item_id,           --34077520002
        IMPL_DATE => V_DATE,
        unit_number_from =>null,
          unit_number_to=>null,               
        ERR_MSG => v_err_msg,
        ERR_CODE =>v_err_code,
        organization_option =>1,
        organization_hierarchy =>null,
        serial_number_from =>null,
          serial_number_to =>null
end;
Now I query the table BOM_SMALL_IMPL_TEMP and it shows the data as per the structure of the item where used.
NOW ALL I WANT IS I WANT TO CALCULATE EXTENDED QUANTITY  (PARENT-QTY * ITS_CHILD_QTY)
CURRENTLY IT SHOWS ONLY COMPONENT QUANTITY. HOW CAN I CALCULATE EXTENDED QUANTITY LIKE WE DO IN BOM EXPLOSION?
Can any one help me on this?
Thanks,

Thanks , Yes it works but need to work out.
I have used rather calling API and then query using this-
select t1.*,
DECODE(T1.PART,T1.PART,(SELECT DISTINCT SEGMENT1 FROM MSI WHERE INVENTORY_ITEM_ID = T1.PART)) LOWEST_ITEM,
DECODE(T1.PART,T1.PART,(SELECT DISTINCT DESCRIPTION FROM MSI WHERE INVENTORY_ITEM_ID = T1.PART)) LOWEST_ITEM_DESC,
t2.segment1 PARENT_ITEM,
T2.DESCRIPTION PARENT_DESCRIPTION,
T2.ITEM_TYPE PARENT_ITEM_TYPE,
DECODE(T2.ORGANIZATION_ID, 125, 'MU1', 126, 'MU2') ORG_CODE,
T3.ITEM_COST,
T1.QTY*T3.ITEM_COST EXTENDED_COST
from
(select t.*
         from (WITH t AS (SELECT distinct SYS_CONNECT_BY_PATH(a.parent_item_id, '\') || '\' || a.current_item_id || '\' as path,
                                          a.component_quantity qty_per_assembly
                            FROM BOM_SMALL_IMPL_TEMP1 a,
                                 mtl_system_items_b      b
                           where a.parent_item_id = b.inventory_item_id
                             and b.organization_id = a.organization_id
                           START WITH b.item_type IN ('SA','FG MFG')
                          --CONNECT BY  a.current_item_id = PRIOR a.parent_item_id
                          CONNECT BY nocycle a.parent_item_id = PRIOR
                                     a.current_item_id)
                SELECT root_part, part, SUM(qty) AS qty
                  FROM (SELECT SUBSTR(t1.path,
                                      2,
                                      INSTR(t1.path,'\', 1, 2) -
                                      INSTR(t1.path, '\', 1, 1) - 1) as ROOT_PART,
                               SUBSTR(t1.path,
                                      INSTR(t1.path, '\', -1, 2) + 1,
                                      INSTR(t1.path,'\', -1, 1) -
                                      INSTR(t1.path, '\', -1, 2) - 1) as PART,
                               (SELECT EXP(SUM(LN(t2.qty_per_assembly)))
                                  FROM t t2
                                 WHERE t1.path LIKE t2.path || '%') AS qty
                          FROM t t1
                         GROUP BY t1.path)
                 GROUP BY root_part, part) t
               where t.part = :lt_part
       ) t1,
      mtl_system_items_b t2, CST_ITEM_COSTS T3
where t1.root_part = t2.inventory_item_id
AND T1.PART = T3.INVENTORY_ITEM_ID
AND T2.ORGANIZATION_ID = T3
.ORGANIZATION_ID
   --and t2.item_type = 'FG MFG'
   and t2.organization_id = :lt_org;
and now it is running perfectly
